I guess what I am most interested in is who everyone would pick to play the main parts.

Roland: I think that Karl Urban would make a good Roland. He is a pretty good actor and he totally nailed Woodrow Call in Comanche Moon. Of course, a 50 year old Clint Eastwood would be the ideal candidate, but that's not possible.

Eddie: I heard someone mention Jensen Ackles and I think that would be a good match. He can be a goof or a stone cold killer at any given moment.

Susannah: The only one that I can really think of that would likely do this part justice is Zoe Saldana.

Jake: This part would likely have to be a virtually unknown up-and-comer. Haley Joel Osment would have made a good Jake but he's too old now.

For some reason, I have also always pictured Cort as a grizzled Robert Duvall.
